Looking for a Domain Model

I am looking for a Domain Model which I can download. It is no matter which kind it is as long as it is well designed and has solved a lot of different problems.

It should have Business Objects like Article, Order and so on.

I want to build a ERP framework so I need something for testing.

Do you know where I can get such a Domain Model?
